2019 Bmw X3 Complaints

Rear caliper locking up when in reverse. Knocking noise and crunching sound.

My 2019 BMW X3 equipped with a B46 engine developed a significant coolant leak at approximately 80,000 miles. The vehicle displayed a low coolant warning, and coolant was visibly leaking underneath the vehicle. Around the same time, I began noticing excessive white exhaust/steam during cold starts and, for the first time since owning the vehicle, had to add engine oil between scheduled oil changes. The vehicle is currently undergoing inspection by an independent repair facility. Preliminary findings indicate concerns involving premature failure of critical plastic cooling system and/or oil filter housing components. Based on my research, these failures appear consistent with widespread complaints involving BMW B46/B48 engine cooling system and oil filter housing defects. I am concerned this defect could lead to sudden coolant loss, overheating, engine failure, or unsafe driving conditions. Prior to the coolant warning appearing, there were no significant alerts indicating a major or...

Our 2019 BMW X3 M40i shows "EMERGENCY CALL SYSTEM MALFUNCTION" which means the "SOS" system, which is crucial for post-collision response, fails. Erhardt BMW in Bloomfield Hills, Michigan confirmed water leakage due to defective sealing around the roof-mounted shark fin antenna damaged the Telematics Control Box (TCB) and now requires replacement. The estimated cost is $3,600. Some quick research revealed this to be a repeated problem with my vehicle. BMW has acknowledged it as a defect in 2017-2023 model year BMW M440i, M550i, X1, X3, X4, X5, X6, X7, 330, 340i and 750i vehicles and fix it at no cost, but only for citizens of [XXX] , as reported by [XXX] of [XXX] .

I'm reporting a safety issue with BMW vehicles equipped with the B58 engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drive train malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants...

Main dashboard display is partially blocked by a message stating “emergency call system malfunction.” Apparently the roof mounted antenna’s seal fails and allows water into the electronics for the emergency call system. Upon failure, it also stops the Bluetooth microphone for the cell phone to stop working. The dealer quoted the repair at $3,200. Judging from a google search, this is a common problem among this generation of BMW vehicles.
